DOWNLOAD A DATASHEET

Amphenol Fiber Systems International (AFSI) offers the TACBeam® Fiber Optic Modem (FOM) to provide optical-electrical (O-E) and electrical-optical (E-O) conversion for harsh environments. This stand-alone unit features ruggedized optical transceivers integrated in a compact housing with single or dual T1 RJ48 electrical interfaces (additional electrical interfaces available − consult factory) and AFSI’s TACBeam® 4-channel expanded beam connector.

The “plug and play” unit allows systems engineers to effortlessly convert their systems to take advantage of the benefits of fiber optics without the need to design and develop harsh environment fiber optic transceiver electronics. The TACBeam® FOM’s compact size also significantly reduces the footprint devoted to O-E and E-O conversion.

The standard TACBeam® FOM provides conversion for G.703 T1 (1.544Mb/s) electrical signals via a standard RJ-48 to multimode optical signals via AFSI’s TACBeam®. The TACBeam® is qualified to the M83526/20 & /21 specification and uses expanded beam technology to reduce the impact of particulate matter on the optical performance. Expanded beam technology also facilitates the cleaning of the connector, reducing maintenance costs and improving up-time. Because the connector faces do not touch, the TACBeam® can be mated/demated more frequently than traditional physical contact connectors.

Features

  • Effortlessly converts systems to fiber optics (longer distances, EMI/RFI immunity, lighter weight) without major system design/redesign
  • Compact size significantly reduces O-E/E-O conversion compared to traditional discrete designs
  • Harsh environment transceivers support extended temperature range and military vibration/shock requirements
  • Converts single or dual T1 signals (two or four fibers)
  • Qualified with MIL-PRF 83526/20 & /21 optical interface and G.703 T1 electrical interface
  • Expanded beam technology decreases the impact of particulate matter on optical performance, lowers maintenance costs and increases up-time
